TO ALL W'HOM IT MAY CON CERN:

Be it known that I, D. SAVALLE, ot' Paris, France, have invented certain Improvements in Distilling- Apparatus and I do hereby declare the following to be a full, clear, and exact description of the same.

nMy invention consists of a certain apparatus, constructed as fully described hereafter, whereby crude alcohols and other liquors may be quickly distilled and purified, with the use of but` little if any water for condensing, and with `a better result than-with the ordinary apparatus.; the appara-tus beingr simple, inexpensive, not liable to get out of order, and requiring butlittle attention during its operation.

In order to enable others skilled in the art to make and use my invention, I will new proceed to describe its construction and operation, reference being had to the accompanying drawings, which form part of this specification,4 and in which* The figure in Sheet No'. 1 is a sectional elevation of my improved distilling-apparatus, and the figure in Sheet No. 2 is a sectional elevation of a modiiication.

In Sheet No. 1, A is a cylindrical vessel, having a dome-like top, und divided by a horizontal partition, al, into two compartments, A and B. In the compartment A is a coil of steam-pipe, m, which communicates with a steam-generator through a pipe; ml, und in the latter isa throttle-valve, m2. In the compartment B is a per-- forated pipe, a, which communicates, through curved pipes a", with-the compartment A', an overflow-pipe, b, pro- ;eeting from twenty to thirty centmetros above the partition all To the top` ot'` the vessel A is connected an upright tube or column, B, containing a series ot perforated plates or partitions, c c, arranged a short distance apart; the perforations being from eight to twelve per cent. of the surface of each plate; and through each plate extends a tube, d, which projects into a cup-like depression in the partition below it, as shown in the drawing. The upper tube extends about one centimetre above the surface of its plate, and the other tubes increase gradually in length, the lowest being about threecentimetres above the surface of its plate. l

Through the lowest; plate. passes a pipe, n, which extends through the side of the casing A to the casiug of a three-way cock, 1, and with the latter communicate pipes nl l11.2; the pipe 'nl leading to a vessel, O, into which extends a tube, 8,-projecting from the bottom of a vessel, O, and in the latter is a float, o, which is connected by suitable devices to the throttle-valve m2, so that when the oat rises the throttle will close. The column B communicates, through a pipe, g, with a condenserf D, consisting of a. casing divided by two parti` tions, and a seriesof vertical pipes, into two chambers c c', the former being the space between the partitions and' round the pipes, and the latter the-space below the lower partition and within the pipes.

{lhechamber c communicates, through a pipe, L, with the upper part of the column B, and through a pipe, i, with what I term a cleancr, E, which is a cylindrical casing, ihto which the end of the pipe z' projects. A

pipe, il, leads from the lower end of the cleaner E to the pipe fz, and a pipe, from the upper end ofthe casing to a coolerf F.

The cooler F consists of a long casing or tube, closed at the lower end, and divided by two partitions, and vertical pipes k, with two compartments 'c el, the former being the space round the pipes and between the partii tions, and the latter'the space within thepipcs and below the lower partition, and into the compartment el, and

also into the compartment c of the condenser, projects a watcr-pipe, o, having a 'rose" at the inner end.

. Across the cooler extendone or more partitionsf, in which are openings for the passage of the pipes c, the

openings in the upper partition being three millimetres greater in diameter than the pipes,l and those in the lower partition one millimetrc greater.

The crude liquor'is placed in the lower compartment A of the casing or heater A, steam is admitted to the coil m through the pipe ml, and the vapor which rises from the heated material passes through the pipes q a to the chamber B', the column C, and through the pipe g to the condenser D. Water isnowpassed through the pipe e. to the condenser D, cooling the latter, so that the alcoholic vapors in the same are condensed, and flow through the tube h back into the column, over the plates of which it passes successively until it falls into the compartments B', where it is brought into contact with the vapors from the lower compartment A", which are thus partially purified and condensed before entering the column.

`When the column is charged with liquid, the passage of cold water to the condenser is so regulated, that i not more than two-thirds of the vapors which pass into the condenser shall be condensed. 'The noncondensed vapors fromthccondenser pass to the separator E, and thence to the cooler F', where they are condensed by the watcrintroduced through the pipe c', and from the lower part of which the condensed liquor is drawn.

Should the pressure within the vessel A be too great, the steam passing through the pipe n into the vessel o, will force a. portion of the liquor in the latter-,into the vessel o', the loat o will rise, and, through the medium of the'devices connected'to the throttle-valve m2, will close or partially close the latter.

In like manner a decrease of pressure in the casing A will cause the lloat to descend and the throttle to he opened, a uniform steamsprcssu're and temperature being thus maintained in the apparatus.

The column of plates in this apparatus differs from those of the ordinary construction, inasmuch as the plates contain different quantities of liquor. In the old columns, the layer of liquor is of the same depth on each plate, and. varies from iivc to eight centmetros in height., which gives these plates a capacity of from live to eight centmetros, cube, of liquid for a. centimetro, square, ofVplate-surface. In the above-described column,

the tubes d are so arranged that the capacity of the plates varies from one to five centimctres. cube, of liquid to a centimetro, square, of p1atc-surface,the proportion of liquor increasing successively on each plate towards the By this arrangement a much more rapid passage of the liquor through the column is effected, the quality of the product is improved, and the operation is completed in less time.

In somecolumns it may be advantageous to diminish the extent of the pcrforations in the upper plates. As the openings in the plates C are from eight to twelve per cent. of the arca of the plates, the vapor can pass upward more freely than in the ordinary columns where the openings do not exceed four per cent. of' the area ot` the plates, the operation ot` the apparatus being thus greatly accelerated.

Owing to the construction of the condenser D, but a very small amount ot' water is required to eliectA a rapid condensation-of *the* vapors, while the proportion of vapor condensed may be regulated at pleasure. If desired, the condenser may be arranged with its tubes in-a horizontal position.

The cooler F is constructed in a manner very similar to the condenser, and with a like result, much less water being required than in coolers of the ordinary construction. Where a constant supply of water for the condenser or cooler is difficult to obtain, the modification illustrated in drawing No.2 may bc u sed.

In this apparatus there is but a single chamber below the column B, and the tube g from the upper end ot' the latter passes directly into a cleaner, E, which serves to receive foam and particles carried with it from the column, and prevents those sudden shocks which constantly derange ordinary apparatus; the vapor passing l'rom the cleaner through a tube, z'2,to the upper end of the cooler F. rlhis cooler is closed at the top, and communicates, through a pipe, with a. reservoir containing the liquor to be distilled. This liquor passes into the lower part of the cooler rises to the upper end through thc tubes k, and passes through the pipe x to the upper part of the column B, while the vapor passing from the cleaner E, enters the space in the cooler surrounding the tunes, and is' cooled byimparting its heat to the cooler and to the liquor in the same; thcliquor thus reaches the column in a heated state.

i It will he seen that by this arrangement, the use of' water for condensing and cooling the vapor is dispensed with. The above apparatus is superior to those of the ordinary form, inasmuch as it costs less to construct, works more rapidly, there is less loss of alcohol, and better product is obtained.

The crude alcohol may be purified by passing it through a mass of charcoal, and the alcohol may with advantage be conducted from the condenser through a mass of charcoal before passing it again into the column. The rectieation by this means is distinguished from a. rectification of crude alcohol, not purified, in that the product is incr in quality, greater in quantity, and of a better flavor.

I am aware that heating-chambers have been used in combination with columns containing perforated platesx through which extend short vertical tubes, and I am also aware that condeusers and coolers have been used in connection with the said heaters and columns; .I thereforelay no broad claim to an apparatus containing such parts, or to the parts separately but I claim as my invention, and desire to secure by Letters Patent--` 1. The combination, with the column B, of a. casing, A, divided int two compartments A' B', the lower containing a heating-pipe, m, and the upper a perforated pipefa, or its equivalent,` substantially as and for the purpose described.

2. Graduating the size of the openings in the perforated plates of the column, and the length of the tubes which extend above said plates, substantially asiand for the purpose specified.

3. The casing O, communicating with the heater A, or with its column, in combination with the casing O, its tube s and iloat'a, connected to the throttle-valve m2, the whole being arranged and operating substantially as and for the purpose described. Y

The arrangement,in respect to the heater A and column B, of a cooler, F, consisting of a casing divided by partitions and pipes into two compartments, one communicating with the column, and the other with the water-pipe 0*, as set forth. i h

In testimony whereof, Ihave signed my name to'this specification in the presencc'of two subscribing witnesses.
